Question

我正在使用NestJS，我有一个控制器，该控制器从引发异常的服务中调用异步方法，如下所示：

@Get('gde/expedientes/:expediente/caratula')
  async readExpedientesCaratulaFromGDE(@Param('expediente') expediente: string): Promise<readCaratulaResultType> {
    return await this.client.readExpedienteCaratula(expediente)  // this throws an Exception!
  }

该服务只会引发常规的JavaScript错误，而不是NestJs HttpExceptions。

我希望全局处理程序能够捕获它，但是http客户端只是挂起，并且在服务器中出现以下错误：

我确实是throwing inside of an async function without a catch block，但我希望Nest能处理此问题。我想开发自己的全局处理程序，并捕获“请求问题：getaddrinfo ENOTFOUND xxx.xxx.xxx”错误。

是否有某种方法可以捕获它，还是应该将控制器方法始终包含在try / catch块中？
